Abstract
When user data is recorded on a write-once medium, linking variations can be reduced that are produced as management information for managing the user data is updated by additionally recording on and off, thereby assuring the reliability of the reproduction compatibility of the DVD player. Before the final file of the management information is recorded, dummy data of a plurality of successive blocks are recorded at a time by a single operation, and then the final file is additionally recorded after the dummy data. Therefore, the linking precision can be prevented from being degraded in the linking portions of the management information, and thus the management information can be properly read when the DVD player makes compatible reproduction of the medium.
Description
Technical field
The present invention relates to the recording technique of data to recordable CD.
Background technology
CD can write down bulky information and possess the interchangeable feature of recording medium.
In various CDs, handle DVD (the general digital CD: of the high capacity information of so-called computing machine, reflection, music Digital Versatile Disc) as the new huge storage capacity recording medium of PC, AV machine etc. and make one notice with same recording medium, reproduced popularizing of special-purpose DVD phonograph, by coming on stage of the DVD recorder that also can write down, enlarging market hastily.
Be accompanied by popularizing of recording type optical disc, the interchangeability of CD is much accounted of as user's hope.; DVD-Random Access Memory), (DVD-can write down DVD-RW again: DVD-ReWritable) etc., but can not reproduce usefulness and do not have the CD that the DVD-RAM etc. of interchangeability rewritable format writes down with the DVD phonograph but (the DVD random access memory: because the DVD-RAM of the rewritable format that many DVD phonographs of extensively popularizing are not supported in the DVD recorder to be adopted.Therefore its trend is, (DVD-is recordable: DVD-Recordable) formulation of specification is as the wedge machine, wants by supporting to guarantee high interchangeability as the medium of the DVD-R of recording type optical disc as the DVD-R of benchmark with the DVD-video form.
Under the situation of real-time recorded data, before whole card identifying recording layer stops,, often have or the power supply of interrupting device in the moment of record arbitrary data, or from the situation of device taking-up dish and so on.At this moment, continue, guarantee writing afterwards of new data, be necessary the data at disc recording till this moment are managed in order to make the data that write down.Therefore when carrying out data recording, then the management information (IFO file in the middle of being called later on) that is used to manage this dish is upgraded.
At Fig. 1, during with document form recording image contextual data, the state that middle IFO file is upgraded is shown on DVD-R.Usually, the posting field of dish according to its kind, is divided into the management information areas 2 of the file of recorded data on the zone (being called image information zone 1) of user data and the management dish.Fig. 1 (a) illustrates the position relation of file on DVD-R of middle IFO file when recording video scenery 2 and each video scenery.According to writing afterwards the file 4 of video scenery 2 with the file 3 continuous ways of connecting of image 1.Because the file 4 by writing afterwards video scenery 2, the file build on the dish changes, so record is used to upgrade the middle IFO file 2 (symbol 5) of new management information.
Because DVD-R is the write-once medium, so can not writing as the middle IFO file that record is new on old middle IFO file.Therefore, even under the situation of new administration information more, also similarly write afterwards, so that be connected continuously with the data of last registration with image information zone 1.The middle IFO file of therefore, writing afterwards at last should illustrate the file build on the up-to-date dish.
Fig. 1 (b) and Fig. 1 (a) join, and further write afterwards the file of video scenery, insufficient space because of the dish capacity is shown, can not be write afterwards the state of video scenery by the file 6 of video scenery N.At this constantly, the file build on the DVD-R is finished, and the information of managing this state is illustrated by middle IFO file N (symbol 7).Therefore, if IFO file N (symbol 7) in the middle of reproducing, but then to the file access of whole video sceneries.
, at the DVD phonograph, under the state of Fig. 1 (b), can not reproduce.This result from utilize that precompressed is made, with the equipment energy characteristic of the DVD phonograph that is reproduced as supposition of DVD-ROM dish.The format specification of DVD-ROM is from interior circumferential periphery helically recording image information etc.For during the DVD-R disc recording, exchange to reproduce at the DVD phonograph, same with the dish of DVD-ROM form, be necessary not comprise continuously ground records such as non-recorded part from interior week.
The user stops the record of data (file), in order to be produced on the dish that can exchange reproduction on the DVD phonograph, is necessary to carry out end process.In case carry out end process, shown in Fig. 1 (c), be the form of benchmark according to form with DVD-ROM, add the middle IFO form (symbol 7) of final updating again, as final management information (being called final IFO file 8 later on).The DVD phonograph is obtained the file build on the dish by reproducing this final IFO file 8, can carry out access to each image data.Unrecorded part is filled up with empty data 9, forms from interior week filling full state with some data continuously.Under such state, can reproduce the DVD-R dish with the DVD phonograph at the very start.
During the file of each IFO file or video scenery continued to write afterwards, between these files, produce the joint that is called connection.About this connection, further specify with Fig. 2.At this figure, be that example is illustrated with dish with 80 μ m off-centre.
Fig. 2 (a) illustrates by write afterwards the video scenery file, the skeleton diagram of the connecting portion that forms on dish.The top portion that writes afterwards record data 12 opening entries during with the start-of-record that writes down shown in the connecting portion 13 of Fig. 2 (a) up to the terminal part of the record data 10 of last time (the N-1 time) and image data (the N time).
Aspect the reproduction exchange on DVD phonograph etc., guarantee high reliability, require the such connection of Fig. 2 (c) ideally.; because the influence that dish is eccentric; even under same rotating speed, rotate; linear velocity in orbit also changes; so during the synchronizing signal record data that obtain from dish; or produce such Unrecorded gap portion shown in Fig. 2 (b), or opposite with it, produce data lap 16 each other such shown in Fig. 2 (d).
Since with the recording medium destructing of the such write-once of DVD-R the data of lap 16 among the data of record, can not be by ECC (error correcting code: Error Correcting Code) mistake is corrected.In case this lap 16 is interval elongated, then also servocontrol is exerted an influence.In addition, then opposite so that also servocontrol is not exerted an influence in order to correct mistake if plan to reduce overlapping 16 parts to the greatest extent by ECC, be easy to generate Unrecorded gap portion 15.
At the lap 16 of data of record, under the such write once recording medium situation of DVD-R, the data of original record have been destroyed and both sides' data of the data during writing afterwards, write.As the prior art of considering this problem, open to disclose on the flat 9-270171 communique the spy and skip, only nearby insert empty data, losing of information be suppressed to the gimmick of minimum at connecting portion as empty data with the ECC data block that comprises connecting portion.Here, so-called empty data refer to image data or management information one class has the data of some meaning different in data content, and it is the data that do not have the data content meaning.
In addition, producing between data and the data under the situation in Unrecorded gap 15, original data and the data both sides that write afterwards do not have to destroy, then under the situation of the DVD phonograph that reproduces special machine, owing to adopt the servocontrol that DPD (differential phase detection) mode of having utilized record mark is arranged, so can not be servo in addition at non-recorded part, the information of playback record normally.
As other the prior art of considering this problem, in order to reproduce the recording medium of recordable type with the DVD phonograph, open the method that discloses record on the flat 11-25459 communique the spy, so that make the data terminal portion of the top portion of the data of writing afterwards and aforementioned recording section overlapping, and do not produce Unrecorded gap.
Summary of the present invention
Yet, only rely on above-mentioned prior art, during few file such as the data volume of writing afterwards record IFO file etc., often can not keep high connection precision.Below set forth its reason.
When writing afterwards the file of IFO file or video scenery,, be necessary according to becoming certain benchmark synchronization in order to produce the moment of record start position.This benchmark with synchronizing information (SYNC) as benchmark.SYNC has two kinds, has the recording method of using these two kinds of SYNC respectively.The 1st be with on dish in advance the synchronizing information (for example LPP-SYNC) of record as the recording method of benchmark.The 2nd is the recording method as benchmark of the synchronizing signal (for example synchronous code (SYNCcode)) that comprises in the data with former record.
Usually, on certain part of record data, the recall rate of LPP-SYNC is low.Therefore, synchronous with the synchronous code (SYNC code) in the data that write down, adopt the method in the moment that produces record start position.
This can be appreciated that: if with the synchronous code that makes data portion (SYNC code) synchronization, produce the recording method in the moment of record start position, the file that the repeating data amount is few, for example be recorded in the writing afterwards of IFO file of management information areas 2, the variable quantity that can continue to enlarge connecting portion is then arranged.With Fig. 3 this mechanism of production is illustrated.
Fig. 3 (a) be illustrated in write afterwards take place during the management information, connecting portion changes the figure of an example.Fig. 3 (b) illustrates the synchronization position in the generation moment during the management information of writing afterwards separately and the variation of record start position.
At Fig. 3, the variation maximum of record start position gets ± 10T (T for short message wide), N initial data 17 are regarded as LPP-SYNC and the data that write down in synchronous code (SYNC code) be in the correct position relation.In addition, think that the synchronous code (SYNC code) of decision moment of record start position and preceding 2 data produces synchronously.For the convenience that illustrates, the N～N+5 data volume is regarded as all identical.
Here, think moment of the start-of-record that produces synchronously with preceding 2 synchronous codes (SYNC code) respectively, data 18 and N+4 data 20 at N+2, record start position is done the variation of 10T in the hysteresis direction, and in N+3 data 19 and N+5 data 21, record start position is shifting to an earlier date the variation that direction is made 10T.
The variable quantity of the record start position of writing afterwards for the 1st time, the 2nd time is 10T, yet, shown in Fig. 3 (a), on the connecting portion between the data 19 of the data 18 of N+2 and N+3, produce the overlapping of 20T, on the connecting portion between the data 20 of the data 19 of N+3 and N+4, produce the Unrecorded gap 23 of 30T, in addition, on the connecting portion between the data 21 of the data 20 of N+4 and N+5, produce overlapping 24 of 40T.By this figure as can be seen, the variation of connecting portion is accompanied by to write afterwards and overlaps and enlarge.
The main cause that produces so big variation be because; Produce the data and repeatedly data synchronization sign indicating number (SYNC code) generation synchronously of (more than 2 times) preceding record in the moment of start-of-record.The synchronization that is generally used for producing the moment of record start position is necessary according to record start position, seeks since 2～dozens of ECC data block (the ECC data block is the data record unit of disc recording) is preceding.This is for SYNC that the data flaw that prevents by record produces does not detect, flase drop goes out, and guarantees the reliability that SYNC detects.
Therefore, the influence that some the data recording starting position that is subjected to easily to have write down when the writing afterwards of few data such as the data volume of 1～2ECC data block degree of management information etc. changes, as the file of video scenery, by the big variation that also is easy to generate the record start position of writing afterwards data of writing afterwards of the many data of data volume.
Especially, the present inventor finds, during record final IF08 shown in Figure 1, causes above-mentioned described problem, see the kind of DVD phonograph, can not correctly read management information sometimes, but have can not the identification dish property.
Summary of the invention
The purpose of this invention is to provide the information recording technique, it can suppress the variation of the data recording position in gap between so-called data overlapping, the data each other, improves the reliability of data reproduction.
In order to achieve the above object, in the present invention, for carrier that can not overwriting data, with the synchronizing signal that obtains from carrier as benchmark, information recording method for record data, the empty data of record on carrier, with the synchronizing signal of in empty data, preserving as benchmark, the management information of record management aforementioned data.
In the present invention, for on the carrier that can not rewrite with the information recording method of predetermined recording records data in units, at the carrier identifying recording layer, make benchmark with the synchronizing signal that obtains from carrier, with the empty data more than at least 2 records of operation of recording record unit once and the management information of management aforementioned data.

Embodiment
Below, as the information record carrier that is suitable for the 1st embodiment of the present invention, enumerating with the DVD video camera at DVD-R disc recording video scenery (animation picture) or rest image is that example is illustrated.As the purposes of DVD video camera, because the situation that the video scenery of 10 seconds units of logarithm or rest image are repeatedly photographed is many, number of times of promptly writing afterwards and out of Memory pen recorder are more more, are suitable for the present invention, and are preferred., much less out of Memory pen recorder is even DVD phonograph for example also is the scope of application of the present invention.
Fig. 4 is among the DVD video camera that illustrates as embodiments of the invention, the block scheme that the part relevant with the DVD-R data recording constitutes.Present embodiment is made of master controller 25, modulation portion 26, record data generating unit 27, moment generating unit 28, recording portion 29, recapiulation 30, data discriminating portion 31, detuner 32.These each square frames are controlled by the control circuit of not shown CPU etc.
Below, the action when writing down is illustrated.The data of the data of 25 so-called video sceneries of record of master controller or management information, empty data are sent to modulation portion 26.Modulation portion 26 coding (error correcting code ECC) that additional error correction is used on the data of record is this data conversion the data of other form.For example carry out 8 bit data are transformed to 8/16 conversion of 16 bit data.Record data generating unit 27 is based on the data of 8/16 conversion, and generation is with the record data of the pulse form of NRZI form 2 values of high (Hi) level and low (Lo) level.As the NRZI signal of record data and the record that produces by generating unit 28 constantly synchronously, be sent to recording portion 29 constantly.Constantly generating unit 28 with from the synchronizing signal of data discriminating portion 31 as benchmark, produce record constantly.Sequentially be sent to recording portion 29 at moment generating unit 28 and the synchronized record data of synchronizing signal.Recording portion 29 constitutes by the photohead that is made of semiconductor laser device driving circuit, semiconductor laser, optical system, travel mechanism, and record data are sent to semiconductor laser device driving circuit, drives semiconductor laser and makes laser instrument luminous.The laser beam that penetrates from photohead shines the recording film plane of CD, forms record mark.Empty data can not transmit from master controller 25 yet, are stored in advance by modulator 26.
During reading the data that store on the CD, undertaken by recapiulation 30.Recapiulation 30 is photoheads identical with recording portion 29, concentrates on the CD that record is over by the laser a little less than than record the time, detects the reflected light of modulation by record mark.Recapiulation 30 outputs are as the reproduction data of the information that writes down on the CD and the servosignal of tracking or gathering control necessity etc.Reproducing data is differentiated by the user data that 31 pairs in data discriminating portion illustrates the synchronizing signal (SYNC figure) of data demodulates starting point and image information etc.User data is sent to master controller 25 by detuner 32 demodulation.Also can determine to detect the synchronizing signal (example: LPP-SYNC), also can detect the synchronizing signal (example: synchronous code (SYNC code)) that comprises in the data of former record that on above-mentioned CD, writes down in advance in data discriminating portion 31., because the synchronizing signal that writes down in advance on dish is difficult to reproduce behind record data, so preferably decision detects the synchronizing signal that comprises in the data that formerly write down.
IFO also upgrades for 50 times in the middle of with the dish of the user data of the camera record video scenery of master controller 25 50 times being.The variation of the average record start position that connects for 1 time is in ± 10T in.In the image information zone, shown in Fig. 5 (a),, also can not enlarge the variation range of connecting portion even repeat to write afterwards.Its reason be because: the data capacity of image information is big, for once the record the ECC data block (at present embodiment, the ECC data block is the record unit in the data of disc recording) several many, write afterwards the moment of the start-of-record of data, do not produce by soon not comprising the image data portion that writes down before the connecting portion.
, the IFO file as management information is that the data block number that once writes down is the 2ECC data block.And, since moment of its start-of-record produce by the IFO file of most the fronts of having write down, so with moment of the form decision start-of-record of the connection error of accumulating its part.
Therefore, shown in Fig. 5 (b), repeat to write afterwards, the variation range of above-mentioned connecting portion continues to enlarge at every turn.Write afterwards in the data that existing mode was carried out, be mostly the situation of writing afterwards, because the number of times of writing afterwards at this moment is degree several times at most, so can not discover this class problem in the purposes of so-called program recording or SoundRec.This just begins to discover by the present inventor.
In addition, can see also that the connecting portion variation of the IFO of record often reaches about 40T when finally finishing after 50 scenes according to present inventor's experiment.Experiment shows, surpasses about 30T from the connecting portion gap width, according to the kind of DVD phonograph, can not normally reproduce.
Therefore, as can be seen,, the connecting portion of the final IFO that the DVD phonograph reproduces is changed accomplish below the 30T for the reliability of the data reproduction that improves the DVD phonograph.
At the information record carrier of present embodiment, shown in Fig. 6 (a), behind final IFO, or not to insert empty data, but shown in Fig. 6 (b), between middle IFO7 and final IFO8, to insert the form of empty data 33, at the DVD-R identifying recording layer.In addition, for the moment that optical disc apparatus produces start-of-record, empty data 33 increase necessary data block number, and are more particularly, big than 2 record units, for example 2ECC data block.The position of each file by producing middle IFO as shown in Figure 6, final IFO, empty data concerns, the movement concept when writing down final IFO8 as shown in Figure 7.
Between the intermediate file and empty data 33 of the 50th scene, overlapping or the clearance portion of maximum generation ± 40T.On the other hand, by inserting empty data 33, the start-of-record when writing down final IFO8 (being made of VIDEOTS.IFO file 37 and VIDEO_TS.VOB file 38 and VIDEO_TS.BUP file 39 and VTS_01_0.IFO file 40) detects synchronous code (SYNC code) and the synchronization in the sky data 33 constantly.Therefore, owing to produce constantly, so can produce record under the same terms constantly writing afterwards with the file of the big video scenery of data volume according to the data (empty data 33) that before not comprising connecting portion, write down.Therefore, the precision of connecting portion is identical with shown in Fig. 5 (a), the variation 34 of the connecting portion of final IFO can be suppressed at ± 10T in, can improve the reliability of data reproduction.
Here Shuo Ming embodiment be with improve so-called by the DVD phonograph to the reliability reproduced with the exchange of the data reproduction of DVD camera record as purpose, in order to improve the reliability of self reproducing, even when the record of middle IFO, also can adopt same technology.
Follow after middle IFO existing not the inserting empty data of mode, write down under the situation of final IFO, in 10 pieces of dishes, 1 piece probability is arranged, the deviation of about 40T degree takes place on the coupling part of final IFO, its result has by the irreproducible situation of DVD phonograph.In contrast, use result of the present invention, at the connecting portion of final IFO portion owing to can suppress deviation in 10T, so can realize the reproduction of no problem.
Below, for using the 2nd embodiment of the present invention to be illustrated.Just change the order of data recording, because the formation of information record carrier self is identical with the 1st embodiment with action, so omit its explanation.At the 2nd embodiment, individually be recorded in VIDEO_TS.IFO file 37, VIDEO_TS.VOB file 38, VIDEO_TS.BUP file 39, VTS_01_0.IFO file 40 record, that constitute empty data file 33 and final IFO file 8 when finalizing a text separately.Fig. 8 illustrates action in this case.When the data of record management information file separately, record reference position constantly by with identical empty data file 33 in the synchronous code (SYNC code) that has synchronously, produce, can intactly use the record controls of existing mode, and the variation of connecting portion is to the maximum ± 20T, can reproduce with the DVD phonograph no problemly.Because this recording method can realize by existing recorded control, so compare with the 1st embodiment, obtain above-mentioned effect easily.
Below, for using the 3rd embodiment of the present invention to be illustrated.Same with the 2nd embodiment, because the formation of information record carrier self is identical with the 1st embodiment with action, so omit its explanation.At the 3rd embodiment, shown in Fig. 9 (a), be not behind final IFO, to insert empty data, but as Fig. 9 (b) shown in empty data and final IFO as 1 data 35, once write down empty data and final IFO, Figure 10 shows action in this case.
Between the middle IFO file and empty data 33 of the 50th scene, identical with the situation of the 1st, the 2nd embodiment, overlapping or the clearance portion of generation maximum ± 40T.On the other hand, with empty data and final IFO as 1 data record on DVD-R.Start-of-record when the final IFO8 of record (being made of VIDEO_TS.IFO file 37 and VIDEO_TS.VOB file 38 and VIDEO_TS.BUP file 39 and VTS_01_0.IFO file 40) detects synchronous code (SYNC code) and the synchronization in the middle IFO that has write down constantly, yet because between empty data and final IFO connecting portion itself does not take place, so obtain the effect identical or better with the 1st embodiment.
At present embodiment, be illustrated for example with the record of final IFO file, yet, much less can be suitable for the present invention no matter data class how, calculates the record short data of data necessary length constantly as long as repeated to write afterwards than being used to.
Be illustrated for example with DVD-R, yet so long as, be the scope of application of the present invention the information record of the recording medium that can not rewrite.
In addition, the formation of information record carrier also is not limited to formation shown in Figure 4, also can be to detect synchronizing signal from the recording medium of wanting record data, calculates record constantly and formation that can record data by this synchronizing signal.
